Arduino mega with HCM5883L

Okey, so i got QMC that act like/close to HMC at the most, only the status register won't work...

1. Question
You mentioned, that i need to disable status register acces. I think you mean i need to uncomment the acces line in the libraray itself. But wich line i need to uncomment, can you help me?

or

2. Question
My sketch already got delay between the measurements like this:

unsigned long currentMillis = millis();
    if (currentMillis - previousMillis >= interval) {
      previousMillis = currentMillis;
      Vector norm = compass.readNormalize();

Where interval = 500 ms

So if i uncomment the status register access line in the library, and keep this delay methond, then it will be fine?
